Sounds like bad IAC...

you are right, the APC is turbo-related. In my 93 turbo, there is no IAC as the electronic throttle system takes over. I remember the tales of resurrected IACs from the pre-trionic days but never was obliged to try it myself on my 89. From what I remember, though, there was a point of no return which many an IAC reached. Sounds like yours has a resistance problem which causes it to stick shut when energized.
I don't remember if they are expensive or not; if so you might have okay luck harvesting a used one.
Is your system still the LH 2.x setup? I wonder if you might be compatible with older models and possibly save a little?
